Halophytes are plants that live in saline soils. The high osmotic potential of the salt solution in the soil creates a very negative water potential. What can halophytes do so that water will flow into the roots

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

1. is geographic distribution

2 is increasing complexity

3 is transitional forms

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
